Attached are the two key mappings from xev. They show that the 4.19.y kernel has proper keysyms for the keyboard, but the 5.10.y do not. However, both kernels provide the same keycodes since those likely come directly from the keyboard.

FAVI keyboard is mapped using xmodmap in /etc/X11/xinitrc:

# If using the Favi keyboard, adjust mouse acceleration
# and remap Arrow Keys to KeyPad arrow keys
# This remap only works on PiBox/RaspberryPi cuz the keycodes
# are different on other distributions.
if [ -f /etc/init.d/data/usb.list ]
then
    FAVI=`grep 1997:2433 /etc/init.d/data/usb.list`
    if [ "$FAVI" != "" ]
    then
        xinput --set-prop 6 'Device Accel Constant Deceleration' 2
        xmodmap -e 'keycode 198=KP_Up'
        xmodmap -e 'keycode 200=KP_Left'
        xmodmap -e 'keycode 201=KP_Right'
        xmodmap -e 'keycode 204=KP_Down'
    else
        xinput --set-prop 6 'Device Accel Constant Deceleration' 3
    fi
else
    xinput --set-prop 6 'Device Accel Constant Deceleration' 3
fi

This means that the FAVI is not being seen in the usb.list. A quick check of usb.list shows that it does NOT have the FAVI in it, though if you run lsusb manually it shows up. So the lsusb that generates the usb.list is run before the keyboard is found.

The fix is to run lsusb in xinitrc manually instead of relying on usb.list, since usb.list is generated before all drivers are loaded.

That fix worked. The fix went into pmsui, which contains the xinitrc used or the media player (and other) systems.

Tested, committed and pushed.

Closing issue.
